A 51-year-old male with acute lymphoblastic leukemia whose course was complicated by primary fibrinolysis and spontaneous rupture of the spleen is described. The patient was treated with various drug combinations: vincristine and prednisone, later by cytosine arabinoside and finally by prednisone, methotrexate and 6-mercaptopurine. Four months after the diagnosis he developed epistaxis and petechiae. The coagulation tests were compatible with primary fibrinolysis and he responded to treatment with epsilon-aminocaproic acid (EACA). One month and a half later he developed again epistaxis, ecchymoses, splenomegaly and an acute abdomen. The coagulation tests revealed primary fibrinolysis. The operation revealed a ruptured spleen. After splenectomy the treatment with EACA was continued and, despite an improvement in the coagulation tests, the patient died.

Wandering spleen is an unusual entity, occurring in both sexes and at any age, but is more frequent in women of reproductive age and in children. Wandering spleen is probably most often a result of congenital anomalies of development of the dorsal mesogastrium, but acquired factors may have a role in certain instances. Patients present most commonly with an asymptomatic mass, mass and subacute abdominal or gastrointestinal complaints or with acute abdominal findings. Clinical diagnosis can be difficult, but noninvasive imaging procedures, such as sonography, nuclear scintigraphy, computed tomography and magnetic resonance imaging are usually diagnostic. Laboratory tests are usually nonspecific, but may occasionally reveal evidence of hypersplenism or functional splenia. Symptoms may remain limited or absent for long periods of time, but complications related to torsion or compression of abdominal organs by the spleen or the pedicle are quite common. Splenomegaly is usually a result of torsion of the pedicle and splenic sequestration. Significant morbidity and mortality rates seem to be considerably less than described in 1933 and limited primarily to patients presenting initially with acute abdominal findings. Management recommendations have varied, but recognition of a significant risk of postsplenectomy sepsis supports a conservative approach. Patients with limited symptomatology may be medically managed until they exhibit worsening symptoms indicating progressive splenic torsion or gastrointestinal compression. Detorsion and splenopexy may be considered a reasonable surgical option even in patients presenting with acute abdomen, if there is no evidence of infarction, thrombosis or hypersplenism. Splenic preservation is especially recommended in extremely young patients who are at particular risk for postsplenectomy sepsis. However, it should be noted that follow-up evaluation data on splenopexy patients are notably lacking. Splenectomy is ideally reserved for patients presenting with acute abdomen and splenic infarction or thrombosis or with hypersplenism and patients in whom splenopexy is technically unfeasible. Subtotal splenectomy and splenic autotransplantation may be of limited value. Pneumococcal, Hemophilus and meningococcal vaccines are indicated before elective splenectomy and shortly after nonelective splenectomy. Antibiotic prophylaxis is recommended for those at particular risk. Prospective studies are unlikely, but extended follow-up information on patients already reported, particularly those managed expectantly or with conservative surgical measures, is needed.

Recombinant human (rh) granulocyte-macrophage colony-stimulating factor (GM-SCF) is currently being tested in clinical trials for the treatment of acute myeloid leukemias with two main intentions: reduction of neutropenia and recruitment of leukemic blasts into cell cycle to enhance cytarabine (ara-C) mediated cytotoxicity. We report a case of a fatal spleen rupture in a patient with acute monocytic leukemia (AML M5b) who was treated according to a clinical phase I/II protocol with rh GM-CSF priming and standard induction chemotherapy TAD 9 (thioguanine/ara-C/daunorubicin). During treatment we observed rapidly rising peripheral blast counts and the development of an acute abdomen. Ultrasound examination revealed splenomegaly due to diffuse cellular infiltration and spleen rupture. The patient died 17 days later due to pneumonia and renewed spleen hemorrhage. Bone marrow progenitor assays before treatment showed exclusive growth of monocytoid blast cell colonies (CFU-L). Colony growth could be stimulated with rh GM-CSF and blocked dose-dependently by a monoclonal anti-GM-CSF antibody. CFU-L proliferation also increased after stimulation with rh interleukin-3 (rh IL-3) and supra-additively with rh granulocyte colony-stimulating factor (rh G-CSF) combined with rh GM-CSF. Furthermore, rh GM-CSF induced surface marker expression of CDw 65 and CD 11b on isolated CFU-L blasts. After short-term suspension culture, rh GM-CSF enhanced the expression of CD 29- and CD 11b-adhesion molecules on peripheral blast cells. In summary, this case represents a fatal spleen rupture occurring during rh GM-CSF priming and induction chemotherapy for acute monocytic leukemia. Although the etiology of this spleen rupture remains uncertain, in view of our data we suggest special caution, when further testing this therapy protocol in acute leukemias with monocytic subtype and high peripheral blast cell counts.

Two adults and a child with acute abdomen and surgically confirmed torsion of wandering spleen are presented. Computed tomography provided a spectrum of findings including an ovoid or comma-shaped abdominal mass, hypertrophy of the liver's left lobe, a whirled appearance of hyperdense, nonenhancing splenic vessels, and an enlarged spleen, exhibiting minimal or no enhancement. Computed tomography also indicated the point of torsion and the viability of splenic parenchyma.

We report a case of a spleen infarction caused by the vascular pedicle torsion. A 25 year-old-man, heterozygous for HbS, presented with severe abdominal pain especially in the left upper quadrant in front and in the back, fever other symptoms related to acute abdomen. First we excluded most common disease (occlusive one and hematologic one) through conform investigation, then we suspected a spleen problem. So we did further investigation with ultrasonography which showed splenomegaly and the spleen looked twisted with its hilum in contact with previous abdominal wall, moreover (here were are as of decreased signal intensity characteristic of splenic infarction under the capsule and some blood in the Douglas pouch. The patient underwent splenectomy urgently. During the intervention we saw a splenomegaly like the ultrasonography showed, moreover there were a long twisted vascular pedicle and many areas of infarctions, some of which had ruptured causing emoperitoneum. The surgical intervention was successful and the clinical spectrum was solved. The splenic infarction might be clinically silent or to represent a surgical emergency. In front a case of acute abdomen, after exclusion of most common etiology, we underline the importance to suspect a spleen suffering, especially vascular one, when (here was no history of trauma. Considering this fact, a simple not invasive examination like ultrasonography is able to confirm this kind of hypothesis and to give soon information to make the surgical choose.

Surgical therapy of the acute abdomen often allows only limited time for differential diagnosis to confirm the indication for surgery. Under consideration of clinical aspects and case history both common and rare causes of an acute abdomen should be investigated without undue loss of time. Differential diagnostic considerations and eventual therapy are presented in the following case of a 25-year-old Afro-american who developed multiorgan failure after an initial course of lower-back pain. In addition to the clinical setting of an acute abdomen the patient presented with acute respiratory failure and laboratory signs of severe hemolysis in combination with newly detected splenomegaly. The indication for splenectomy was made following CT-proven complete splenic infarction due to repeated acute squestration. Histologic examination of the spleen together with hemoglobin electrophoresis confirmed the clinical assumption of unusually late primary manifestation of a sickle cell crisis. In the underlying case, the hemoglobinopathy was in fact the less common form of combined sickle-cell-beta-thalassemia. A ten-day course of intensive care therapy was necessary to treat ongoing multiorgan failure due to persistent sickle cell crisis. Current diagnostic and therapeutic procedures in connection with sickle cell crisis as a rare cause of an acute abdomen with the necessity for surgical intervention are presented.

Pooling of blood in the spleen is a frequent occurrence in children with sickle cell diseases, particularly in the first few years of life, resulting in what is termed "splenic sequestration crisis." The spectrum of severity in this syndrome is wide, ranging from mild splenomegaly to massive enlargement, circulatory collapse, and even death. The diagnosis is usually clinical, based on the enlargement of the spleen with a drop in hemoglobin level by > 2 g/dl, and it is rare that imaging studies are ordered. However, in the patient who presents to the emergency department with non-specific findings of an acute abdomen, it is important to recognize the appearance of sequestration on imaging studies. We studied seven patients utilizing contrast-enhanced CT scans and found two distinct patterns--multiple, peripheral, non-enhancing low-density areas or large, diffuse areas of low density in the majority of the splenic tissue. Although radiological imaging is not always necessary to diagnose splenic sequestration, in those situations where this diagnosis is not immediately obvious, it makes an important clarifying contribution.

The torsion of spleen on its vascular shank represents an uncommon problem, responsible of acute and chronic pain. The mobile spleen is fixed only through hilus vessels the gastrosplenic ligament. The incidence is unknow, greater in the male with an M:F ratio 6.1 in the first ten years of life, even if an episode of intrauterine torsion has been reported. The diagnosis can be performed with ultrasonography, angiography, scintigraphy and CT scan. There are reported two cases: male of 2.5 years female of 14 years who presented with recurrent pain to the left side, vomit diarrhoea and fever. Objectively a palpable mass was present. Ultrasonography and angio-CT scan of abdomen revealed splenomegaly, ptosis of the spleen and malrotation with signs of obstruction of the vessels. The treatment in both cases was splenectomy. The spleen appeared rotated on its shank and increased of volume, deprived of anatomical structures of fixation. The histological report confirmed the haemorrhagic infarction. The excessive mobility of the spleen, from insufficiency or absence of the ligamentous attachments is case of abdominal pain or acute abdomen, that can complicate with the infarction of the spleen. Angio-CT scan, in the cases here reported, has shown to greater sensibility in comparison to the ultrasonography. The Authors believe that the video-laparoscopic splenopexy, when the diagnosis is made of "wandering spleen" with painful repeated episodes, can be finalized, to the preservation of organ.

Wandering spleen is a rare medical entity. It usually occurs at 20-40 years of age, and most cases are seen in women. Clinical diagnosis is difficult due to lack of symptoms, unless splenic torsion has occurred and clinical symptomatology of acute abdomen develops. The diagnosis can be confirmed by imaging techniques. Treatment is operative due to complications of splenic infarction. Splenopexy is the usual treatment, except for cases of splenic infarction. Splenectomy should be carried out when there is no evidence of splenic blood flow after detorsion of the spleen and in cases of excessive splenomegaly.

Wandering spleen is a rare cause of acute abdomen. Generally, it remains asymptomatic, it may present clinically as a painless mobile mass or rarely as an acute abdomen when the wandering spleen twists on its pedicle, resulting in splenic congestion, infarction with or without involvement of neighbouring visceras. Here, we present an unusual case of torsion of a wandering spleen, which resulted in congestive splenomegaly and small bowel obstruction as a rare case of acute abdomen.
